Detailed Description

Capabilities iterator.

A forward iterator over a libsolv id array. Automatically skips internal dep-marker ids, setting the tagged flag when it does so to indicate that subsequent capabilities carry a special property (e.g. pre-requires within a solvable's requires list).

Member Function Documentation

tagged()

bool zyppng::sat::Capabilities::const_iterator::tagged ( ) const

inline

Return true if the Capability is tagged.

The meaning of tagged depends on the kind of dependency you are processing. It is a hint that the iterator skipped some internal marker, indicating that subsequent capabilities have a special property. Within a Solvable's requirements e.g. the pre-requirements are tagged.

Capabilities req( solvable.dep_requires() );
for ( auto it = req.begin(); it != req.end(); ++it )
{
  if ( it.tagged() )
    cout << *it << " (is prereq)" << endl;
  else
    cout << *it << endl;
